Question

A conducting current-carrying plane is placed in an external uniform magnetic field. As a result, the magnetic induction becomes equal to $B_1$ on one side of the plane and to $B_2$, on the other.

Determine the direction of the current in the plane in the case illustrated in above figure.

• A. clockwise
• B. counter clockwise
  
• C. spirally downward
  
• D. none of these
  

Answer 1

The correct option is A clockwise

Make a screw rule with right hand and the direction of magnetic field is clockwise and hence direction of current in plane clockwise.
